Title: Method for the production and application of replacement stringing for tennis racquets
Inventor: REPPERT RUEDIGER LOTHAR VON
IPC: A63B49/038
Filed: 1981-05-07
Abstract: It occurs very frequently in tennis that strings break during play in the stringing of the tennis racquet used, so that in some cases the game has to be continued with another racquet of different stringing tension. Consequently, a new tennis racquet has been developed which permits the immediate replacement of the stringing, the frame of the racquet being divided as far as the heart of the racquet, forming an opening approximately 3 to 10 mm in width. A twin frame with the same, or any desired, type of strings and stringing tension can then be inserted into the racquet laterally or from the top and secured there by means of counter-sinkable screws or a clamping device, by means of which it can also be released again and removed from the racquet.

Title: Device for transferring powered face support assemblies
Inventor: PIRAGS SIEGFRIED
IPC: E21F13/00
Filed: 1981-06-05
Abstract: To fluidically supply movable consuming devices from a fixed supply line, hitherto use has been made of flexible supply hoses which roughly have the length of the roadway of the consuming devices and are mostly guided in a loop shape and/or via additional deflection trucks with counteracting cable. The effort required for correct operation is considerable. The susceptibility to trouble is great. According to the invention, a supply line (3) is installed for the consuming devices of a transport assembly (1) for transferring powered face support assemblies from a gallery to the site of installation in the longitudinal direction of its roadway (2). Tapping points (4) for the attachment of connecting hoses (5) are integrated in the supply line (3). The connecting hoses (5) can be coupled to a storage drum (6) of the transport assembly (1) via a rotary lead-through (7). The rotary movement of the storage drum (6) is derived from the positive guidance of the transport assembly (1) via a gear transmission and a slip clutch. The coupling facility between the supply line (3) and the storage drum (6) via the connecting hoses (5) avoids complicated loop formations and deflection trucks including the auxiliary devices. The gear transmission keeps the connecting hoses (5) taut over one half of the travel, whereas the slip clutch keeps the connecting hoses (5) taut over the other half of the travel. <IMAGE>

Title: Mechanical and hydraulic energy convertor
Inventor: WILLIG KURT
IPC: F03G7/10
Filed: 1982-06-19
Abstract: This energy convertor is very simple in its design and production. The bolts can be stressed using very long springs or, even better, can be hydraulically pressed because of the uniform stressing of all bolts. The only problem is that, according to my geometrical considerations, the bolts cannot be pressed cleanly from the inclined plane alone. I have therefore sought assistance from the wheel. If it is desired to raise a bolt using an inclined plane, as the slope of the plane increases it is necessary to add further counterforces to the pure lifting weight.
